What should I do if Mac OS X Yosemite appears Wang Yu bug?

Mac OS X Yosemite new bugs, so users can play pranks again, but beware of no friends! As long as you enter a specific string, the various text boxes on your Mac will crash to the end, and even some apps can only remove the reload.

It is important to note that this text appears in the edit box only to cause a crash, and there is no problem with simply displaying it. And according to feedback, not every device will have problems, the specific reasons are unclear.

In order to protect the world peace, today's small part of the original version of the bug is a screenshot processing, lest you like a small series spread cancer everywhere.

As for the solution, the more relaxed one is to use CLEANMYMAC or similar software, using the "Reset App" function, you can restore the damaged application to normal, but all the data of the software will be lost, please be careful.

As for the manual method, you can try to delete all the files under ~/library/container (~ represents the app name), but all the data will still be emptied.
